How old is your oldest tour shirt?

I recently went through my garage because I was packing to move and found a box that was filled with live concert tour shirts in it. At one point, I must have boxed things away so that I could move or make more room or whatever. But 30 years later, here's my concert T shirts from 1992. So I can't be the only one that has old shirts. So now I'm curious, what's your oldest?

Soldier Field 1992. Still fits I think I'm almost proud of that.
